Description MikeC 2020-04-25 09:25:17 UTC
SUMMARY
With telepathy-kde 20.04-1 plasma desktop login via sddm has a delay of around 30 seconds after initial desktop loads before the panel loads and login completes

STEPS TO REPRODUCE
1. Upgrade plasma kde-applications from 19.12.3-1 to 20.04-1
2. Login to plasma desktop
3. Login begins but hangs for around 30 seconds before the panel appears and login completes.

OBSERVED RESULT
Login has additional abnormal 30 second delay

EXPECTED RESULT
Login should complete almost instantly as normal

SOFTWARE/OS VERSIONS
 
Linux/KDE Plasma: Arch Linux telepathy-kde* 20.04-1
(available in About System)
KDE Plasma Version: 5.18.4.1-1
KDE Frameworks Version: 5.69.0-2
Qt Version: qt5-base 5.14.2-1

ADDITIONAL INFORMATION

May be unrelated but the telepathy-kde-meta package for the previous version was missing:

$ ls /var/cache/pacman/pkg/telepathy-kde-meta*
/var/cache/pacman/pkg/telepathy-kde-meta-19.12-1-any.pkg.tar.xz
/var/cache/pacman/pkg/telepathy-kde-meta-20.04-1-any.pkg.tar.zst

Workaround:

Downgrading all telepathy-kde packages to 19.12.3-1 except telepathy-kde-meta resolves the problem, and login to the plasma desktop becomes fast and normal again.
Comment 1 David Roth 2020-04-25 10:56:11 UTC
To be a bit more specific the KdedIntegrationModule seems to timeout during invocation

Comment 2 MikeC 2020-04-25 12:01:20 UTC
Yes I have the analogous entry in my log:

$ sudo journalctl -b -1 | grep KdedIntegrationModule

Comment 3 answer2019 2020-04-25 18:51:45 UTC
same here.
Distr: Gentoo.
affected package kde-apps/ktp-kded-module (KDE Telepathy workspace integration)
& some more symtoms: in ps ax listed: Z  0:00 [dbus-daemon] <defunct>  
+ freezed krunner after launched plasma panel
Comment 4 Lex Onderwater 2020-04-26 13:58:15 UTC
Ran into a similar issue but than with Krunner waiting 2 minutes for KdedIntegrationModule to be loaded. Turns out that the module filename is incorrect, so a quick fix is:

$ cd /usr/lib/qt/plugins/kf5/kded/
$ sudo ln -sv ktp_integration.so ktp_integration_module.so

Comment 7 MikeC 2020-04-29 15:51:21 UTC
The workaround in comment #4 creating a soft link for ktp_integration_module.so does resolve the problem for me also.  Perhaps it is simply a typo in the source code that results in this issue?
Comment 8 MikeC 2020-04-30 19:12:10 UTC
This issue is resolved in the updated package: telepathy-kde-integration-module 20.04.0-2
